Answer: -The mean is not affected by the existence of an outlier.


Step-by-step explanation:

An outlier is an ultimate value in a set of data that is very much higher or lower than the other numbers. Mean is the only central tendency which is affected by the outlier. (It also affect the standard deviation)

It can affect the mean of a data set by skewing the results so that the mean is no longer representative of the data set.

The median and the interquartile range is unaffected by the existence of an outlier.

<em>Make the unknown numerator be x and unkown denominotor be y</em>

<em>We have :  7 - </em>\frac{x}{y} = 6\frac{4}{5}

            =>       \frac{x}{y} = 7 - 6\frac{4}{5}

                       \frac{x}{y} = \frac{1}{5}

<em>So we need to fill in the box :</em> \frac{1}{5}

<em>If the answer is helpful, Brainliest please!</em>

Devon wants to write an equation for a line that passes through 2 of the data points he has collected. The points are (8, 5) and
ser-zykov [4K]
For this case we have the following equation:
 7x - 10y = 3&#10;
 From here, we must substitute ordered pairs of the form:
 (x, y)
 If the ordered pair satisfies the equation, then it belongs to the line.
 We have then:

 For (8, 5):
 
We substitute the following values:
 x = 8&#10;&#10;y = 5&#10;&#10;7 (8) - 10 (5) = 3&#10;&#10;56 - 50 = 3&#10;&#10;6 = 3
 We observe that the equation is not satisfied and therefore, this point does not belong to the line.
 Since one of the points does not belong to the line, then the equation is not a good model.

 Answer:
 
It is not a good model. One of the points does not belong to the line.
